I bet your mileage really sucks in the Winter then... Half your trip is spent warming up the engine, and as it gets up to temp, you shut it off. That alone will simply kill your mileage, and as I mentioned, in the Winter it will be even worse. Unfortunately there's not much you can do about that, it is just the way things work. Most people don't notice how much gas is wasted during warm-up because it averages out over a longer trip.

My recently purchased '05 EXT LT , 127,000kms (79k miles) is running completely stock right now, with 245/65/17 Hankook ATs at 35 psi, and 3.42 gears. I checked mileage, from full tank to full tank, on a 425 km (265 mi.) run the other day, with 40% freeway at 75 MPH, 40% mountain 2 lane at 60-65 MPH, and 20% logging roads, some in low range, at low speeds, less than 20 MPH. The trip average was 16.2 MPG(US) or 20.2 MPG Imperial. I think that's pretty good for a truck of this size and weight, especially since I don't hypermile, but drive for fun and performance, so I'm a bit heavy on the throttle, but smooth. My buddies were impressed with both the highway and logging road performance, and comfortable all day, which is saying a lot, as the combined age of the 3 of us is 229 years!

Surprisingly low for a stock vehicle. I get about 15.5 MPG (US) pretty regularly with 70% highway usage, and can get into the 16.5-17 mpg range if I keep my speed low on the interstate. Well, at least before the new roof rack, it probably stole another .5 from me.

Converted to US gal, my latest tank was 16.54 mpg, which seems to be what most other posters in the thread are reporting. Some with larger tires are getting an extra couple of miles, obviously the higher effective gearing helps them out.
